Caltrans Report: Speeding and Aggressive Driving Cause Most Crashes

Caltrans crunched four-year-old collision data from the California Highway Patrol and found that nearly twenty percent of traffic-related fatalities and severe injuries are speed-related.

In the 2013 report, the most recent year for which data is available, more than 71,000 collisions were attributed to speeding. Likewise, rear-end collisions occurred far more often than “sideswipes,” the second-leading type.

But, the article continues,

Despite these seemingly large numbers, traffic-related fatalities on California’s highway system — and the nation as a whole — are actually continuing a downward trend.

That is, measuring since 1995, collisions resulting in fatalities and severe injuries declined by as much as 25 percent, despite a small uptick between 2010 and 2013.

Also unfortunately, the Mile Marker doesn’t help interpret the data. Why, for example, are rear-end crashes far and away the most common type? Could it have something to do with distracted driving? Or maybe it’s because drivers feel invulnerable after years of safety efforts that have focused on the occupants of cars–with airbags and seatbelts–but not on the people they hit?

And why, oh why, is Caltrans still calling crashes “accidents”?

This Mile Marker also charts progress towards some of the department’s 2020 goals, including reducing pedestrian and bicycle fatalities—and let’s just say, there is a ways to go on that one. Fatalities rose between 2012 and 2013, rather dramatically, instead of dropping. What’s happened in the four years since?

The Mile Marker is a newish way for the department to get information out to the public about what it’s up to and why. Other articles in it don’t rely so heavily on old data. They include discussions of the California Sustainable Freight Action Plan and this year’s state budget, great photos of artworks on highway underpasses, and an outline of the California Transportation Plan 2040’s recommendations for reaching state greenhouse gas emission reduction targets.

My solution was to switch to transit once additions to the rapid bus network made it a viable option for my commute and many other trips. I let the bus drivers deal with the other drivers most of the time now.

Wrong. Wrong. Wrong. More bike lobby propaganda. Everyone knows all the collisions are caused by people on bikes rolling stop signs in clear intersections. Duh.

Yet in places like the San Fernando Valley, from what I understand it’s pretty much impossible to give someone a speeding ticket. Perfect!

The primary factor in a rear-end collision is “Following to closely” – its pretty much in the phraseology. Yet somehow, Caltrans attributes rear-endings to speed, while you attribute it to distractions. May be the people behind you were paying complete attention, maybe they weren’t. But it is certain that at least some of them were following too closely!

IMO, not maintaining sufficient distance can manifest in both rear-ending someone and being rear-ended yourself. If you notice someone sucking on your exhaust, the onliest thing to do is gradually ease off the gas and double the distance in front of you. If they don’t back off, keep dropping your speed very very gently. People who tailgate are usually impatient types – they will change lanes and overtake. Don’t know what would have saved you from this particular incident, but in general the more you can avoid being tail-gated, the less likely you are to be rear-ended.

“Why, for example, are rear-end crashes far and away the most common type? Could it have something to do with distracted driving?

Four years ago I braked to avoid a vehicle that cut me off and got rear-ended by the next four vehicles behind me. It’s obvious in so many ways that way too many drivers are not paying attention. Distracted driving is a much bigger problem that DUI and should have comparable penalties.

Caltrans has always said that one of its main concerns was the safety of road users, but its focus has been squarely on people in cars, to the detriment of others. The department developed a notion of safety that led it to encourage straightening and widening roads in response to high speeds and crashes, which […]

Each year, motorists on American streets kill nearly 5,000 pedestrians. The loss of life is enormous — equivalent to 12 jumbo jets crashing with no survivors — but the steady drumbeat of pedestrian fatalities doesn’t register as an urgent public safety crisis. Maybe it would seem more urgent if the press covered pedestrian deaths as […]

Crossposted from City Observatory. WASHINGTON, DC – Citing safety concerns, today Secretary of Transportation Anthony Foxx announced he was contemplating the closure of roads to all private vehicles in nearly every city in the country until he could assure the nation’s drivers that they would be safe behind the wheel. The announcement comes on the […]
